Bisphenol A (2,2-bis(4-hydroxyphenyl)propane, BPA) is widely used as an ingredient in the manufacture of epoxy carbonate, poly carbonate and polyester styrene. Recently, some chemicals which are structurally similar to BPA (BPA related compounds: BPs) are coming to be used and it is reported that they have estrogenic activity on aquatic organisms. In this study, we determined the ability of Portulaca oleracea to remove 6 BPs (BPA,BPB,BPE,BPF,BPP and BPS)from water samples. When the initial BPs concentrations were 1 ppm, these BPs were eliminated in order of BPE > BPF > BPP > BPB > BPA > BPS from the water samples after 48 h. BPE(98.2%) was the highest, and BPS(71.2%) was lowest. At least 2 degradation products were confirmed as degradation products, and they were in order increased with the degradation of BPA.
